Assembling
It is essential the screw is tightened to the correct
torque for fastening the ball in the joint bearing.
• If the ball is loose or badly lubricated, it may
start to move on the pin. This will cause much
wear on the pin.
• There is a risk of overloading the screw when
operating if it is tightened too hard.
1. Lubricate the bearing seatings and studs with
corrosion inhibiting grease.
IMPORTANT!
Only press the outer race when driving in the bearing.
2. Fit the new bearing (1) by carefully driving in the
outer race with a suitable driving or press tool.
3. Fit the circlip (2).
